Just to add to Stefan’s reply, it’s also actually the holiday season and our main forum support person is actually on a well earned summer holiday.

For you stair please note that StairDesigner calculates the stair tread line from first step nosing to the last step nosing. The last step is added automatically but can be ignored when building the stair.

We can send you the dxf files of this stair but please note that you only get one set of dxf files per month so it’s a good idea to make sure that your project is finalised before processing.

In this type of stair it’s important to know how you are going to fix the stair to the floor joists. The fixing will determine the position and size of the first floor landing step.

Hi, we aim to reply to Premium Support subscribers within 24-48 hours, often quicker though, please see the note on the main forum pages. We’ll try to get back to you as soon as possible, often the support we provide is quite technical in nature and we need to check over designs, so it can take a quite a bit of time. Thanks for your understanding. All the best, Stefan

You can create curves stair stringers and cut strings as in you example. However, you can’t actually curve the step nosings, this feature is actually under development.

To draw curves with exact shapes I’d suggest that you first set out the general shape of the stair in CAD and get the XY coordinates of the significant points. These can then be input into the StairDesigner plan. We are working on the possibility to import directly DXF files so this will be easier in the near future.
